The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2404 advisory.

    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols.
    BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing     with DNS); and tools for verifying that the DNS server is operating correctly.

    Security Fix(es):

    * bind: BIND does not sufficiently limit the number of fetches performed when processing referrals     (CVE-2020-8616)

    * bind: A logic error in code which checks TSIG validity can be used to trigger an assertion failure in     tsig.c (CVE-2020-8617)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

The remote CentOS Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2383 advisory.

  - A malicious actor who intentionally exploits this lack of effective limitation on the number of fetches     performed when processing referrals can, through the use of specially crafted referrals, cause a recursing     server to issue a very large number of fetches in an attempt to process the referral. This has at least     two potential effects: The performance of the recursing server can potentially be degraded by the     additional work required to perform these fetches, and The attacker can exploit this behavior to use the     recursing server as a reflector in a reflection attack with a high amplification factor. (CVE-2020-8616)

  - Using a specially-crafted message, an attacker may potentially cause a BIND server to reach an     inconsistent state if the attacker knows (or successfully guesses) the name of a TSIG key used by the     server. Since BIND, by default, configures a local session key even on servers whose configuration does     not otherwise make use of it, almost all current BIND servers are vulnerable. In releases of BIND dating     from March 2018 and after, an assertion check in tsig.c detects this inconsistent state and deliberately     exits. Prior to the introduction of the check the server would continue operating in an inconsistent     state, with potentially harmful results. (CVE-2020-8617)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Security Fix(es) :

  - bind: BIND does not sufficiently limit the number of     fetches performed when processing referrals     (CVE-2020-8616)

  - bind: A logic error in code which checks TSIG validity     can be used to trigger an assertion failure in tsig.c     (CVE-2020-8617)

An update of the bindutils package has been released.

This update for bind fixes the following issues :

Amended documentation referring to rule types 'krb5-subdomain' and 'ms-subdomain'. This incorrect documentation could mislead operators into believing that policies they had configured were more restrictive than they actually were. [CVE-2018-5741]

Further limit the number of queries that can be triggered from a request. Root and TLD servers are no longer exempt from max-recursion-queries. Fetches for missing name server address records are limited to 4 for any domain. [CVE-2020-8616]

Replaying a TSIG BADTIME response as a request could trigger an assertion failure. [CVE-2020-8617] [bsc#1109160, bsc#1171740, CVE-2018-5741, bind-CVE-2018-5741.patch, CVE-2020-8616, bind-CVE-2020-8616.patch, CVE-2020-8617, bind-CVE-2020-8617.patch]

Don't rely on /etc/insserv.conf anymore for proper dependencies against nss-lookup.target in named.service and lwresd.service (bsc#1118367 bsc#1118368)

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2020-0021 for details.

The version of AOS installed on the remote host is prior to 5.15.3. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-5.15.3 advisory.

  - In ImageMagick 7.0.8-43 Q16, there is a heap-based buffer overflow in the function WriteSGIImage of     coders/sgi.c. (CVE-2019-19948)

  - The Broadcom brcmfmac WiFi driver prior to commit a4176ec356c73a46c07c181c6d04039fafa34a9f is vulnerable     to a frame validation bypass. If the brcmfmac driver receives a firmware event frame from a remote source,     the is_wlc_event_frame function will cause this frame to be discarded and unprocessed. If the driver     receives the firmware event frame from the host, the appropriate handler is called. This frame validation     can be bypassed if the bus used is USB (for instance by a wifi dongle). This can allow firmware event     frames from a remote source to be processed. In the worst case scenario, by sending specially-crafted WiFi     packets, a remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
    More typically, this vulnerability will result in denial-of-service conditions. (CVE-2019-9503)

  - An issue was discovered in Rsyslog v8.1908.0. contrib/pmaixforwardedfrom/pmaixforwardedfrom.c has a heap     overflow in the parser for AIX log messages. The parser tries to locate a log message delimiter (in this     case, a space or a colon) but fails to account for strings that do not satisfy this constraint. If the     string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check     that detects invalid log messages. The message will then be considered valid, and the parser will eat up     the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was     zero and now becomes minus one. The following step in the parser is to shift left the contents of the     message. To do this, it will call memmove with the right pointers to the target and destination strings,     but the lenMsg will now be interpreted as a huge value, causing a heap overflow. (CVE-2019-17041)

  - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients. (CVE-2020-12049)
